_D_e_s_c_r_i_p_t_i_o_n:

     This is the default panel function for 'levelplot'.

_U_s_a_g_e:

     panel.levelplot(x, y, z, zcol,
                     subscripts,
                     at = mean(z),
                     shrink,
                     labels = NULL,
                     label.style = c("mixed", "flat", "align"),
                     contour = TRUE,
                     region = TRUE,
                     col = add.line$col,
                     lty = add.line$lty,
                     lwd = add.line$lwd,
                     cex = add.text$cex,
                     font = add.text$font,
                     col.text = add.text$col,
                     ...,
                     col.regions)

_A_r_g_u_m_e_n_t_s:

 x, y, z: variables defining the plot

    zcol: color numbers for each x,y combination

subscripts: which points to draw

      at: cut points

  shrink: either a numeric vector of length 2, or a list with
          components x and y which are numeric vectors of length 2.

  labels: contour labels

label.style: 

 contour: logical

  region: logical

col, lty, lwd: graphical parameters for contour lines

cex, font, col.text: graphical parameters for contour labels

     ...: extra parameters 

col.regions: colors indexed by zcol

_D_e_t_a_i_l_s:

     The same function is used for both 'levelplot' and 'contourplot'
     (which differ only in default values of some arguments). Most
     arguments are self-evident. 'label.style' controls choice of how
     label positions are determined (this is not very sophisticated
     yet). The 'shrink' argument allows the rectangles to be resized,
     proportional to the z-value. The specification can be made
     separately for widths and heights, in terms of a length 2 numeric
     vector, which gives the minimum and maximum proportion of
     shrinkage (corresponding to min and max of z).
